' SHOCK-ABSORBER.

Specification of Application filed July 13,

To all whom it may on cem."

Be itknown that I, GIDEON D. YATES, a citizen of the United States,residing at Lisle, in the conntyof Broome and State of New York, haveinvented certain new and useful Improvements in Shock-Absorbers, ofwhich the following; is a specification.

This invention relates to cushioning devices and has for an object toprovide a shock absorber, for use in connection with vehicles, forcushioning the body of the vehicle. I

. My invention is particularly adaptable to self propelled vehicles suchas automobiles and comprehends, among other features, a device forincreasing the resistance of the carrying spring of the automobile, whenthe same is flexed from normal position, due to an increased weightorpressure being applied to the spring, and particularly when thespringis subjected to a sudden jar or j shock.

In the further disclosure of the invention reference is to he hadlt'othe accompanying drawings, constituting a part ofthis specification, inwhich similar characters of ref;

- erence denote corresponding parts in all the views, and in which,

Figure 1 is a rear elevation of the rear axle of a vehicle showing mydevice applied thereto, ,Fig. 2 is a plan view. Fig. 3 is a verticallongitudinal sectional View taken on the line 3-3 in Fig. 2. Fig. 4 is avertical transverse sectional view taken on the line 44 in Fig. 1. Fig.5 is a perspective view of one of the shackles, showing the ad jnstablearms in detached position, and Fig. 6 is a rear elevation of thefrontaxle of a vehicle having my device applied thereto.

Referring to the views and more particularly to Figs. 15 inclusive, Idisclose the -usual rear axle casing 10 carrying therein a rear vehicleaxle 11, the ends of the said casing terminating in flanges 12 havingformed therewith or secured thereto brackets 13, extending inwardlytoward the casing 1.0 and having pivotal connection with a carryingspring 14: extending over and above the casing 10 to support the body ofa ve hicleQ The carrying spring 14 can be made in any desired shape.orsize convenient to the use thereof and mounted on the carrying spring ona medial curved portion 15 1 thereofis a spring like member 16,consistsprihg 14, at its medial portion, by a vertically arranged bolt',17, extending through the member 16 and; the carrying spring 14, straps18 being arranged to encircle the carrying spring 14, the. member 16 anda crosspiece 19' upon which the vehicle body is adapted to seat, thementioned straps 18 being arranged on both sides of the bolt 17.

The ends of the member 16 are bent to form eyes 20, through which pins21 are passed, the said pins being also passed transversely. through theupper ends of arms 22, mounted to slide in guideways 23, formed in, Ushaped stirrups 24, the said arms 22 and stirrups 24 constitutingshackles 25, with the stirrups 21 mounted to encircle the easing 10. Thestirrups 24 are provided with apertures 26 and similarly the arms 22 areprovided with apertures 27, pins28 being provided to pass through.registering apertures 26, 27 for the purpose of adjustably tsecuring thearms 22 on the stirrups 24. The stirrups 24 are U shaped in crosssection to form the guideways 23, mentioned heretofore, the saidguideways forming seats 29 for the reception of pads 30, preferably-made of leather or the like, the said padsbeing of suilicient thicknessto] project beyond the guideways 23 and engage the axle casing 10. i

In the use of my device, the member 16 will be in normal position whenthecarrying spring 14 is in normal position as shown in Fig. 1. It willnow be readily seen that when the carrying spring 1 1 isv flexed out ofnormal "position, due to a load placed upon the spring or to an upwardmovement imparted to the usual wheels on the axle 11 when one or boththe Wheels strike an 0bstruction, the flexible member 16 will also beflexed out of normal position to exert a check upon the carrying spring,thus cushioning the jar or shock imparted there- 'to. By means of theadjustable connection between the member 16 and the shackles 25, thechecking action of the member 16 can be regulated in proportion to therebound of the carrying spring.

In Fig. 6 I disclose a'fi'ont axle 31 of any usual type and providedwith brackets 32 having pivotal connection with the ends 33 ing of apreferably flat strip of metal of a spring like nature, secured to thecarrying ever, being positioned closer to the centerof the axle 31,whereas in Fig. 1 the brackets 13 are arranged adjacent the ends of therear axle 11. A member 36, similar to the is similar to the operation ofthe member 16 in Figs. 1 to 4 inclusive, the only diflerence being inthe manner of mounting the front member 36 on the front axle 31 whencompared to the mounting of the rear member 16 on the rear axle 14.

The shock absorbing device described can be employed in connection withvarious types of vehicles, although I preferably use the device onautomobiles, particularly those known as Ford automobiles.

Having thus described the invention What is claimed as new, is

1. In combination with an axle casing havin a carrying spring mountedthereon, a flexible member secured to the carrying spring, shacklesencircling the axle casing and consisting of stirrups having armsadjustably mounted thereon and pins on the arms of the said shackles andhaving pivotal connection with the ends of the said member.

2. In combination with an axle casing having a carrying spring supportedthereon, a flexible member secured to the carrying spring and adjustablemeans mounted on the said casing and having the ends of the said memberconnected thereto.

3. In combination With an axle casing having a carrying spring supportedthereon, a flexible member intermediately supported on the carryingspring and adjustable shackles mounted on the said axle casing andhaving pivotal connection with the ends of the said flexible member:

4'. In a shock absorber including a member supported,on--;r. carryingspring mounted onan axle casing, stirrups encircling the said casing,pads on the stirrups and engaging the casing guideways on the saidstirrups and arms mounted to slide in the said guideways and adjustableon the said stirrups, the said arms having pivotal connection with thesaid member.

5. In a shock absorber, the combination with an axle casing, of acarrying spring mounted thereon, a flexible member centrally secured tothe intermediate portion of the 5 ring, stirrups encircling the cas-5mg, gui eways on the stirrups, arms slidable in the said guideways,means for ad justing the arms on the said stirrups, and means pi'votallyconnecting the ends of the said flexible member to the-said arms.

In testimony whereof I afiix my signature in presence of two witnesses.
